According to Paul Bergner, Author of Medical Herbalism. "The usnic acid in Usnea is effective against gram positive bacteria such as Streptococcus and Staphylococcus, making Usnea a valuable addition to herbal formulas for sore throats and skin infections. It is also effective against a bacterium that commonly causes pneumonia Table 19.x shows some conditions that Usnea has been used for in European research."^[12]

There is reason to believe that Usnea, in high concentrations, could possess some toxicity.^[13] The National Toxicology Program is currently evaluating the issue.^[14]
